For Overall Development — Are your shrimps losing color? Do they not look as vibrant as before? Here is your solution – SunGrow Rocks. Our rocks provide the perfect balance for vitality, color and growth, especially for baby shrimps in growing age. They are rich in Calcium that helps shrimp with building stronger shells, and full of Magnesium that is essential for all crustaceans to maintain vibrancy. This product can only be harvested and not made.
Calcium Helps Shedding — Shrimps add vibrancy to your aquatic life and make great pets for both adults and kids alike. And these white rocks that facilitate shrimp’s longevity. Japanese shrimp breeders have a firm belief in stones and they use them in their breeding facilities. You too can beautify your aquarium with these color and age enhancing rocks by SunGrow. A must-have for shrimps, especially Crystal red shrimps, Amano shrimps and Ghost shrimps.
Clearer Water — The stones from SunGrow act as an ion exchanger that clears water in the Aquarium. They enrich water with necessary minerals that enable shrimps to live longer. It even stores substances like heavy metals and ammonium for a longer duration.
Aquarium Decor — The applications of these Rocks don’t just stop here! You can even make use of them in home furnishing by placing them in all the corners of a square or rectangular mirror. Else, place these on the center table of your living room in a bowl filled with water along with a few coloured pebbles, marimos and other plants.
Value Pack — Every pack contains a few pieces of rocks (0.5 inch on an average) surrounded by the rock powder. One pack is enough for a 14 gallon tank and lasts 3 months. So it’s not at all heavy on your pocket. They are small and take very little space. So they are great for your nano tanks too!

Customers say

Customers find these mineral rocks effective for shrimp and snails, noting improvements in shell health and activity levels, while also appreciating their appearance and mineral content. The size receives mixed feedback, with some finding them good for 14-gallon tanks while others are disappointed with their small size. Customers disagree on whether shrimp and snails are interested in the rocks, and there are concerns about dust content, with one customer reporting white dust in their tank. The color enhancement effect is also mixed, with some customers noting brighter colors while others disagree.

    UNIQUE AND COLORFUL!!
    Excellent and responsible Amazon Seller. 3 or 4 of these shrimp arrived DOA (despite seller’s excellent packaging), which is not shocking or surprising and Seller immediately sent me 6-8 replacements! More than fair. My grandkids are mesmorized by these active/unique creatures. Would definitely use again w/out thinking twice!

    No harm to my fish or shrimp
    They look like they do in the pictures. I have no way of testing them to see if they are what they are made out of, but they didn’t dissolve in my tanks. None of the neo or amino shrimp pay attention to them. But they have not caused any harm to my shrimp or did not lose any fish after putting them in.

    So far, it’s doing it says it should do
    So far these are great, nice addition to the tank. There has been a slight change to my ph levels since i got it, hopefully it keeps going up. I have a 10 gallon tank, so I put the whole packet in. It’s not a lot, but its doing its job. They’re pretty solid and havent disintegrated yet, unlike another brand i purchased previously which didnt last 3 days. My shrimp loves it as well.

    Worked but…
    After adding two rocks to my 35gal tank & I’ve noticed my shrimp being able to shed. This was an issue that was causing me to have several dead shrimp. Now they seem to be doing just fine. I didn’t add them all at once. I did not want to shock the tank.Although I noticed a positive difference in my shrimp, half of the rocks had questionable brown markings that almost looked like they were rotting. I throw those away. If that was supposed to be a normal appearance there should be some explanation in the description. I was expecting the rocks to look like the photos and they did not.

    SOAK LIKE THE INSTRUCTIONS TELL YOU TO.
    Really nice, my mystery snails like them! Soaked them for an hour in a bowl to be safe, like with all decorations for my tank.
